Hello,
Can you please help me identify a replacement for hardware shown in photo attached? I believe the stamp says 1.H. I.R. The arm length is 9 inches and the bolt holes are 4" on center.

I believe the closest operator we have that's to yours is our 39-002. Check to see our dimensions line up to yours.
